以原理图设计为例,闸极级(Gate-level)的原理图设计(Schematic Capture)软件包开始出现,功能验证方面,1960年代晚期和1970年代初,开始出现事件驱动逻辑仿真器(Event-driven Logic Simulator)形式的特殊程序。 在闸极抽象层建立数字设计,可以比拟为使用汇编语言建立软件程序,就汇编程序的效率及所需的计算机内存而言,是很好...
Traditional protective relay voting schemes utilize simple logic to achieve confidence in relay trip actions. However, the smart grid is rapidly evolving and there are new needs for a next-generation relay voting scheme. In such new schemes, aspects such as inter-relay relationships and out-of-...
Relay circuits Electromechanical relays may be connected together to perform logic and control functions, acting as logic elements much like digital gates (AND, OR, etc.). A very common form of schematic diagram showing the interconnection of relays to perform these functions is called a ladder di...
This is the buildable, runnable source code for NXSYS (enn-ex-sys) (Version 2), my New York City Subway relay-logic and interlocking panel simulator, and its six offered interlockings, as it stands. It is mine, and mine alone, although Dave Barraza's contributions to its debugging and...
It can realize the functions of analog circuit breaker tripping time setting, three-phase/phase-phase operation selection, input signal logic control, etc., thus simulating the circuit breaker's jumping and closing action.Technical indicators
ZXMN-B Circuit Breaker Simulator is mainly used for the whole set test of power system power failure protection device or complete relay protection screen, which can truly simulate the trip time of circuit breaker device. The tripping and closing of the high voltage circuit breaker ...
Create your control logic. Select "Start," and you're done. Why spend all that time wiring when it's as simple as 1, 2, 3? Your time is valuable and with that in mind, IDEC has created a product that will require very little of it. Using a system smaller than a PLC, with ...
